C.3.3.6. The Monitor section

Each Monitor section configures one type of monitor used by the system. This is an optional entry as most monitors are now detected automatically.
This example shows a typical Monitor section for a monitor: 
Section "Monitor"
  Identifier "Monitor0"
  VendorName "Monitor Vendor"
  ModelName "DDC Probed Monitor - ViewSonic G773-2"
  DisplaySize 320 240
  HorizSync 30.0 - 70.0
  VertRefresh 50.0 - 180.0
EndSection
The following entries are commonly used in the Monitor section:
  • Identifier — Specifies a unique name for this Monitor section. This is a required entry.
  • VendorName — An optional parameter which specifies the vendor of the monitor.
  • ModelName — An optional parameter which specifies the monitor's model name.
  • DisplaySize — An optional parameter which specifies, in millimeters, the physical size of the monitor's picture area.
  • HorizSync — Specifies the range of horizontal sync frequencies compatible with the monitor, in kHz. These values help the X server determine the validity of built-in or specified Modeline entries for the monitor.
  • VertRefresh — Specifies the range of vertical refresh frequencies supported by the monitor, in kHz. These values help the X server determine the validity of built-in or specified Modeline entries for the monitor.
  • Modeline — An optional parameter which specifies additional video modes for the monitor at particular resolutions, with certain horizontal sync and vertical refresh resolutions. See the xorg.conf(5) man page for a more detailed explanation of Modeline entries.
  • Option "option-name" — An optional entry which specifies extra parameters for the section. Replace <option-name> with a valid option listed for this section in the xorg.conf(5) man page.
